-Supportive teatment
-Hep A vaccine or immunoglobulin for post exposure prophylaxis within 14 days of exposure
-Immoglobulin can be used for kids <2 years
-Immunoglobulin can be administered in some high exposure cases or prophylactically, in conjunction with HAV vaccine for those traveling internationally

-Household contacts and sexual partners of known cases
-Oersons accidently inoculated with a contaminated needle
-Newborn infants of infected, jaundiced mothers

-Persons traveling to developing countries for <3 months
-Can give HAV vaccine concurrently with IG if warranted, for those traveling internationally

-Prevention includes:
good hygiene
safe drinking water
HAV vaccine for children 12 months and older
-Children 2–18 years of age who have not received the HAV vaccine may receive the vaccine
-Good hand hygiene with toileting and diaper changes are important to prevent transmission in the home and childcare center

-Highly contagious and preventable with vaccine administered during infancy
-Development of chronic HBV is determined by age of initial acute HBV infection and the rate of loss of HBcAg
-More than 90% of infants infected with HBV develop chronic infection
-Approximately 25–50% of children aged 1–5 years old who develop HBV infections will go on to develop chronic infection

-Transmitted via percutaneous or permucosal exposure, including blood, semen, vaginal secretions, cerebrospinal, and pleural fluid
-It can be transmitted via birth from an infected mother, sexual contact with an infected person, personal hygiene items such as toothbrushes or razors, and infected medical equipment

-Lack of immunization among children who have immigrated to the United States from sub-Saharan Africa and East Asia, or other areas of the world with endemic states of HBV
-IV drug users and those who engage in sexual contact with infected persons -Healthcare workers exposed to contaminated bodily fluids

-Sexual contact or needle-sharing with known HBsAg positive cases, including secual assault or abuse victims
-Individuals with percutaneous or permucosal exposure to body secretions of known cases

-If a mothers HBsAg is unknown before delivery, infants should receive HBV vaccine and HBIG in 2 different sites within 12 hours of birth or 24 hours of blood exposure
-HBIG can be given within 7 days of delivery if the mother tests positive for HBsAg postpartum but its less effective
-Give HBIG and HBV vaccine up to 14 days after last exposure and repeat vaccine at 1 to 6 months for sexual partners of known cases
-In <12 months with household contacts, give HBIG and 3 doses of HBV vaccine
-Hepatitis B vaccine can be used for postexposure prophylaxis if given within 12 to 24 hours after exposure

-HBIG and corticosteroids are not found useful for chronic Hep B

-Hepatitis C infection causes most cases of chronic hepatitis
-About half of people infected with HCV are unaware of their infection and most who become infected with HCV develop chronic hepatitis C
-The incidence of chronic pediatric liver failure increases with the duration of infection

-Transmitted via blood
-The primary source of HCV infections in children is perinatal transmission, however about half of the children who become infected in this way typically see resolution between 24 months and 7 years of age

-Injection drug use
-Men who have sex with men are also at increased risk
-Vaginal births and breastfeeding do not increase the chances of HCV transmission

-Most children with HCV do not exhibit any symptoms
-Older children may have flu-like symptoms, such as nausea or anorexia
-Exam findings may include jaundice and RUQ abdominal pain

-Children with HCV who take acetaminophen or antiretrovirals should be closely followed and their hepatic transaminases monitored
-Children diagnosed with HCV should still receive the HAV and HBV immunizations
-They may still attend daycare as usual
-Discourage alcohol consumption in adolescents and young adults with HCV infection because of the potential for further liver injury
-Education regarding not sharing razors and toothbrushes should be given as well
-Educate young adults about using condoms to prevent spreading the infection if they are sexually active

-Uncommon in children
-It involves concomitant infection with Hepatitis B, as HDV requires the Hepatitis B virus to replicate
-HDV will either be a coinfection or super infection with Hepatitis B
-HDV is transmitted through mucosal, sexual, parenteral, or percutaneous contact with infected blood
-No vaccine is currently available, however, the HBV vaccine also prevents against HDV because of the comorbidity with HBV

-Drug use
-Hemophilia
-Immigration from southern Italy, some parts of Eastern Europe, South America, Africa, and the Middle East

-It can also be found in zoonotic hosts such as swine and nonhuman primates
-It is transmitted through the fecal-oral route, most commonly via contaminated water
-Children are typically asymptomatic or mildly symptomatic
-Older adolescents and young adults are typically symptomatic
-Patients usually make a complete recovery and chronic infections are considered rare
